This patch adds a platform specific DMC620 module derived from core
DMC620 module. Platform specific module is added to address
1. Different register address programming
2. Include DDR DIMM training sequences

This patch removes the dependency on the clock module when
there is no need for a clock to be up and running to start
operating, as it is likely to be on mobile platforms.

If the clocks needed to access the shared RAM memory are
available when the module is started, there is no need to
defer the initialization of the shared data structures
until a clock is locked.

Registers belonging to external nodes cannot be accessed if the power
domain that the node belongs to is not on. We therefore need to avoid
calling `get_node_type()` on external nodes, as doing so will fail.

SGI-Clark has two configurations: one with Ares cores, and another with
Helios cores, which have been given the official product names
Neoverse N1 and E1 respectively.

This patch renames the clark product to better reflect these names,
becoming rdn1e1.

Remove the need to bind to the sid module interface. This enables access
to the system information data during the initialization stage of the
pre-runtime phase. This way, configuration data can be tuned according
to system information data.

n1sdp_sensor module uses timer alarm API for periodically measuring the
sensor values. So the module binds to timer module in the bind stage
using FWK_ID_SUB_ELEMENT call. So when a library is built, the value
calculated by the macro will be taken based on that build environment.

However, in later stage if modules added/removed in firmware.mk, the
position of the timer module will be changed and since a library module
will not be built in normal build phase, it is unaware of the change in
position and hence passes wrong element id to timer during bind. This
makes the code to fail.

As a workaround, this patch moves the id calculation to config file as a
module configuration data so that the value is generated in every build.
The library will read the data passed by the config file and not uses
fixed value.

Duplicating events does not currently zero the list node. This triggers
some of the debug safety checks in the list component when trying to
push the event to a new list, as it will refuse to operate on a node
that it thinks is still part of another list.

This patch ensures that list nodes are always cleared after being
removed from a list. This ensures that functions operating on lists do
not have to manually zero these fields if they need to move the node to
another list.

For PPUs being bound to by system_power instead of power_domain, the
bound_id field was not being updated to reflect the binder. This caused
issues later down the line when trying to use the power domain driver
API of the domain, because the API binding would be skipped if bound_id
was not assigned.

This patch fixes an issue in the support for extended PPU handling in
system_power, where the ext_ppu_apis field represented a pointer to an
API structure, whilst being initialised like a pointer to an array of
pointers to API structures.

This manifested itself in a crash whenever the module tried to iterate
over the array to perform power management tasks.

The CMN600 module does not account for resets of the configured
dependent clock (if any) when allocating context structures or
reconfiguring the network. The consequence of this is that resetting the
clock multiple times will eventually cause invalid register writes, a
heap allocation overflow, and lost allocated memory.

The framework is reset and re-initiated in the setup function such that
the framework is in a known state before the start of each test.
